I despised it in World of Warcraft, but I actually loved it in The Witcher 3. How I feel about it seems to be at least somewhat related to whether it’s a singleplayer game or multiplayer. But it’s more complicated than that - in TW3 without scaling enabled the whole game becomes piss easy even on Death March so it’s kinda required for me to even enjoy the gameplay at all. There are still many ways to gain relative character power that exceeds the level scaling that eventually you just WILL overpower everything regardless.
Unless it’s basically broken I will play games on the highest difficulty possible, because that’s just more fun to me. It makes each game an epic saga and something that can grip my (limited) free time for many many months. Which is good, because I have issues picking up and putting down fictional universes, I get a bit too attached. I don’t get super emotional about it, I just really don’t have the mental energy to deeply engage with something new unless I’m truly done with the last big thing. (I am also neuro-non-standard, I have heard of a term for this, “inertia”)
